Always cool down after you exercise. A proper cool-down will help your heart rate gradually return to normal.

First, gradually slow your intensity for several minutes. Then, stretch –– the best time is right after your initial slow-down since your muscles are still warm. Try holding stretches for at least 20 seconds.

Cool-downs...

- Help avoid fainting or dizziness, which can result from blood pooling in the large muscles of the legs after vigorous activity.
- Reduce the immediate post-exercise tendency for muscle spasm, cramping and stiffness.
